The  principle  of  the  Osborne  bumper  disk  harrow  is  this:  Resistance  of  the  ground  against 
the  action  of  the  disks  pushes  the  gangs  toward  each  other.  Letting  the  inner  ends  of  the 
gangs  touch  and  roll  together  on  large  iron  washers  or  bumpers  at  all  angles  to  which  they  are 

set,  neutralizes  this  force,  reducing 
it  to  nothing.  No  end  thrust  of  the 
gangs  is  carried  by  the  Ijearings  or 
the  frame. 

Bumper  Frame  Without  Joints 

The  inner  ends  of  the  gangs  roll 
together  without  the  necessity  of 
joints  in  the  frame,  as  other  makes 
of  bumper  type  harrows  require. 
Joints  weaken  the  frame  and  sooner 
or  later  become  loose  from  wear. 
Gangs  of  the  Osborne  bumper  disk 
harrow  are  kept  in  rolling  contact 
at  all  angles  by  pivoting  the  frame  a

hold  the  gangs  into  the  ground  instead  of  lifting 
them  upward. 

The  frame  is  of  one  piece  of  angle  steel  stiffened  by 
a  cross  beam  of  the  same  material,  and  two  angle 
steel  pole  bars  which  form  the  stub  pole  for  attaching 
either  a  forecarriage  or  a  stiff  tongue.  This  makes 
a  rigid  frame  which  will  hold  the  gangs  to  do  thorough 
work  in  hard  ground.  The  gangs  are  strongly  braced 
to  the  frame  and  the  set-lever  bars.  These  braces 
form  a  rigid,  triangular  construction. 

An  adjustable  steel  foot-rest,  clamped  to  the  pole 
liars,  makes  comfortable  riding  for  any  size  driver. 
An  easy  seat  with  reinforced  seat  spring  is  attached 
where  the  driver  will  properly  balance  the  harrow. 


Gangs  are  braced  to  the  main  frame  and  to 
the  set-lever  bars 


Strong  Gangs 

The  foundation  of  the  gangs  is  a  heavy,  square  arbor  bolt.  The  spacing  spools  and  the 
disks  have  square  holes  so  that,  should  the  nut  become  loose,  they  could  not  turn  on  the  bolt 
and  cut  it.  The  nut  is  turned  down  very  tight  and  locked  in  place.  Each  spool  has  a  large 
flange  on  the  end  fitting  against  the  convex  face  of  the  disk  to  give  it  support.  The  scraper 
burs  and  weight  boxes  are  supported  at  the  top  of  the  bearing  standards  on  bars  of  angle  steel. 
This  construction  makes  a  solid  gang  that  will  withstand  work  in  the  hardest  ground.

Unassembled  Osborne  bumper  bearing.  The  bearing  casmg  is  shaped  to 

hold  the  octagonal  wood  bushings  in  place.    The  view  shows  the  gang 

pivoted  behind  the  bearing  to  keep  the  bumpers  rollmg  together 

cated  with  the  leiist  attention.  Turning  down  the  cups, 
grease  will  thoroughly  lubricate  the  bearings.  The 
grease  enters  in  the  middle  of  the  bearing  and  is  forced 
around  the  spool,  inside  of  the  wood  bushing.  Grease 
cups  may  be  turned  down  by  hand,  or,  if  necessary, 
with  a  wrench  furnished  for  the  purpose.  The  driver 
need  not  stand  in  front  of  the  harrow  to  turn  down 
the  grease  cups.  It  is  not  necessary  to  carry  an  oil 
can.  Hard  oil  is  the  most  satisfactory  luljricant  for 
the  bumper  type  of  bearing. 

Disk  Blades 

It  is  desirable  to  give  the  disk  blades  as  much 
curvature  as  possible  so  they  will  pulverize  the 
ground  as  it  is  laid  in  the  little  furrows.  This  curva- 
ture is  definitely  limited,  however.  The  gangs  are 
worked  most  of  the  time  at  an  angle  of  about  seven 


Bearings 

Since   the  bearings  of  the  Osborne 
bumper  disk  harrow  do  not  receive  any 
end  thrust,  they  need  be  built  to  with- 
stand   only    the    draft    from    straight 
ahead.    Each  bearing  has  two  octagonal 
wood   bushings   which    are   oil    soaked 
before    being    put    into    place.     Wear 
comes  on  the  rear  of  the  upper  wood 
bushing.     When  this  surface  is  worn, 
the  upper  bushing  may  be  turned,  giving 
a  second  wearing   surface.     Later,  the 
lower  bushing  may  be  exchanged  with 
the    upper,  furnishing    two   additional 
good    wearing    surfaces.     When  worn 
out,  these  bushings  are  easily  and  inex- 
pensively renewed.     The   bearing  case 
is  shaped  to  prevent  the  bushings  from 
turning  on  the  bearing  spool  and  also 
to  keep  dirt  from  entering  the  bearing. 
The  design  of  this  bearing  is  well  suited 
to  its  purpose  and  will  wear  for  a  sur- 
prisingly long  time. 

Bearing  Oilers 

The  bearings  are  fitted  with  hard 
oilers.  These  keep  the  bearings  lubri- 
as  required,  and  keeping  them  filled  with 


Grease  cups  may  be  turned  down  by  hand  when

teen  degrees.  When  set  at  this  angle,  the 
front  cutting  edge  of  the  blade  should  be 
pointed  parallel  with  the  line  of  draft,  and 
the  convex  face  of  the  disk  should  not 
extend  beyond  where  the  edge  will  cut. 
If  it  does,  the  disk  will  ride  on  the  curved 
face  without  penetrating  the  ground  easily. 
Osborne  disk  harrow  blades  are  curved 
to  pulverize  as  much  as  possible,  yet 
penetrate  hard  ground  easily.  This  is  one 
secret  of  their  good  work. 


Set-Lever  Bars 

The  lower  ends  of  the  set  levers  move  in  a  cixrve  as  the  angle  of  the 
gangs  is  changed.  With  straight  set-lever  bars  this  would  put  the  gangs 
out  of  level.  Therefore,  the  set-lever  bars  on  the  Osborne  bumper  disk 
harrow  are  bowed  up  where  the.y  slide  under  the  snubbing  block  to  keep 
the  gangs  level  at  all  angles.  The  snubbing  block  is  adjustable  and  holds 
the  inner  ends  of  the  gangs  down  to  their  work.  By  it  the  gangs  may  be 
leveled  at  an.y  time.  It  is  essential  that  the  gangs  work  level  to  cultivate 
the  ground  to  an  even  depth  the  full  length  of  the  harrow. 

Scrapers 

The  scrapers  are  assembled  with   clips  along  a  square  scraper  bar.      Ai'-steei scraper unassem- 

*  .  .  bled,  showing  how  it  is 

which  operates  the  scrapei's  in  unison  wlien  the  driver  presses  down  the       attached  to  the  square 
scraper  foot  lever.     The  scrapers  move  from  the  middle  to  the  outer 

edge  of  the  disks,  and  clean  them  thoroughly.  Pressure 
against  the  disks  is  regulated  by  a  tension  spring,  and 
may  be  changed  without  tools.  Scrapers  can  be  adjusted 
singly  or  together.  They  are  made  of  a  special  high  grade 
of  steel,  and  are  beaded  or  grooved  in  the  upper  part  to 
strengthen  them. 

Transports 

The  Osborne  Ijumper  disk  harrow  transports  are  simply 
constructed  and  very  quickly  attached.  No  tools  are 
necessary.  The.y  are  made  of  bar  steel  with  wheels  of 
good  size,  equipped  with  hard  oilers.  These  transports 
will  prevent  damage  to  the  disks  in  going  to  and  from 
fields,  and  avoid  cutting  up  the  meadows  or  roadways. 
They  also  hold  the  blades  off  the  ground  when  the  harrow

Osborne  Rival  disk  harrow  with  forecarriage 

The  biggest  features  uf  this  disk  harrow  are  the  great  strength  of  the  frame  and  the  long- 
wearing  qualities  of  the  bearings.  One  piece  of  heavy  bar  steel  forms  the  draw  frame  of  the 
Osborne  Rival  disk  harrow.     This  is  stiffened  by  a  cross  sill  and  two  pole  bars  of  angle  steel. 

The    triangular    construction   of  the 
Jb_  cf.  frame  gives  it  rigidity  the  equal  of 

one  solid  piece. 

The  frames  of  the  large  sizes  are 
reinforced  to  give  additional  strength 
where  required.  The  gangs  are 
attached  to  the  ends  of  the  frame 
at  the  cross  sill  by  heavy  "eye"' 
bolts  which  pass  through  the  l)eai-ing 
standards.  A  Ijrace  from  the  frame 
at  the  cross  sill  extends  to  the  top 
of  the  gang,  foraiing  a  triangular 
connection,  which  adds  to  the  rig- 
idity of  the  harrow.  Another  brace 
frt)m  the  top  of  the  gang  frame 
attaches  to  the  set-lever  bars.  This 
construction  can  best  be  understood 
by  a  glance  at  the  above  illustration. 


The  Osborne  Rival  main  frame  is  triangular  in  shape 

to  withstand  any  excessive  strain  that  may 

come  upon  it  when  harrowing

Gangs  Can  Be  Set  at  Different  Angles 

A  particular  advantage  of  this  harrow  is 
that  the  gangs  can  be  set  at  diii'erent  angles 
for  side-hill  work.  The  bearings  are  con- 
structed to  take  the  end  thrust  of  the  gangs, 
allowing  them  to  act  independently.  When 
di.sking  along  a  hillside  the  lower  gang  may 
be  set  at  a  greater  angle  and  will  hold  the 
harrow  to  follow  the  line  of  draft. 

Strong  Gang  Construction 

The  Osborne  Rival  gangs  are  built  for 
heavy  work.  They  are  strong,  rigid  and 
powerful.  The  gang  frame  is  a  strong  piece 
of  angle  steel  to  which  the  scrapers  and  l^ear- 
ing  standards  are  solidly  bolted. 

The  large  steel  arbor  bolt  upon  which  the 
disks  and  bearings  are  assembled  is  square. 
The  disks  and  si)Ools  have  square  holes. 
Thus  there  is  no  danger  of  the  spools  or  the 
disks  turning  on  the  bolt.  When  the  gang 
is  assemljled,  a  large  nut  on  the  outer  end  of  the  arljoi-  bolt  is  drawn  up  very  tight  and 
fastened  with  a  positive  lock  which  prevents  it  ever  working  loose.  The  spools  are  made  with 
large  flanges,  which  rest  against  the  sides  of  the  disks,  giving  them  added  strength. 


The  gangs  may  be  set  at  different  angles  for 
disking  on  side  hills

Set-Lever  Bars  Bow  Up 

While  the  gangs  may  be  working  at 
different  angles,  they  are  always  kept 
level  by  the  bow  in  the  set-lever  bars. 
This  bow  offsets  the  curve  described  by 
the  lower  ends  of  the  set  levers  when 
changing  the  angle  of  the  gangs.  It  is 
placed  where  the  set-lever  bars  slide  under 
the  adjustable  snubbing  block.  Should 
the  gangs  get  out  of  level,  they  can  be 
quickly  leveled  by  raising  or  lowering  the 
snubbing  block.  The  gangs  should  always 
be  level  to  fill  depressions  and  to  cultivate  to  an  even  depth  on  level  ground.  The  set-lever 
bars  are  always  held  against  the  snubbing  block  by  resistance  of  the  ground  agains*^  the  out- 
throw  action  of  the  disks. 

Durable  Bearings 

The  bearings  of  the  Osborne  Rival  disk 
harrow  take  care  of  all  end  thrust  of  the 
gangs.  This  is  done  by  a  high  ring  around 
the  middle  of  the  bearing  spool  wliich 
turns  in  a  groove  in  the  bearing  standard. 
The  spool  is  made  of  special  hard  iron 
which  practically  can  not  be  worn  out.

Center  Tooth    Cultivates   the   Ridge 

When  diskinji'  once  over,  a  ridge  is  left  by  the 
disk  liarrovv  it'  not  ecjuipped  with  a  center  tooth. 
Tiiis  ridge  is  torn  up  by  the  center  tooth  regularly 
supplied  with  the  Osborne  Rival  disk  harrow.  Its 
good  work  is  shown  in  the  scene  on  page  7.  This 
tooth  is  similar  to  that  of  a  spring-tooth  harrow. 
A  small  lever  and  quadrant  permit  changing  the 
depth  of  cultivation  and  raising  the  tooth  when 
going  to  or  from  fields.  The  Osborne  Rival  disk 
harrow  leaves  a  smooth  field  with  every  part  cT5lti- 
vated  thoroughly  even  when  disking  but  once  over. 

Scrapers 

Adjustable  all-steel  scrapers  of  the  rocking  type 
clean  the  disks  from  the  middle  out  hy  pressing 
down  on  the  scraper  foot  lever.  Pressure  against 
the  disk  blades  is  changed  by  the  scraper  tension 
si)ring  without  the  use  of  tools.  Scrapers  are 
shaped  to  fit  the  square  scraper  bar  and  have 
a  bead  extending  down  the  upper  part  to 
strengthen    them. 

Disks

the    field   with    different   shapes   and    curvatures 


The  center  tooth  can  be  set  at  any  depth  desired 


The  scraper   tension   spring   can   be  changed    without

of  disks    to    determine   the   exact 
used    on    Osborne    disk    harrows 


shape  that  would  do  the  best  work.  This  is  the  disk 
and  is  a  well  balanced  combination  of  a  disk  flat 
enough  to  penetrate  the  ground  and  one  curved 
sufficiently  to  do  good  pulverizing.  The  blades  are  made 
of  a  special  quality  of  steel  which  will  retain  a  good 
edge.  They  are  ground  and  polished,  insuring  that 
they  will  clean  well.

Cutaway  Gangs  for  Osborne  Disk   Harrows 

Cutaway  gangs  for  Osborne  bumper  and  Kival  disk  harrows  will  be  furnished  when  ordered. 
Cutaway  disks  are  especially  adapted  to  working-  in  light,  loose  soil,  because  they  do  not  cut  so 
deep  nor  pulverize  so  finely  as  the  solid  disks.  The  cutaway  gangs  will  make  the  harrow  draw 
easier,  because  it  does  not  cut  with  a  continuous  edge  and  there  is  less  disk  blade  to  be  forced 
into  the  ground.     Scrapers  for  cutaway  gangs  will  also  be  furnished.

The  gangs  are  set  for  in-

frontgangs.  As  the  tandem 
attachment  is  always  work- 
ing on  freshly  harrowed 
ground,  the  disk  blades  are 
cutaway  to  prevent  them 
from  wallowing  l\v  cutting 
too  deep.

The  end  thrust  of  the  gangs  is  outward;  therefore  the  Rival  type  of  bearing  is  used.  These 
bearings  are  fitted  with  hard  oilers  which  keep  the  wearing  surface  well  lubricated.  As  the 
gangs  are  forced  in  opposite  directions,  a  frame  of  heavy  bar  steel,  braced  with  strap  iron,  is 
adopted.  The  gangs  are  pivoted  at  the  corners  of  the  triangular  frame  and  are  set  at  independ- 
ent cutting  angles  by  two  levers  convenient  from  the  driver's  seat.  The  resistance  of  the  soil 
against  the  disks  tends  to  throw  the  outer  ends  of  the  gangs  up.  They  are  held  down  by  two 
loops  of  strap  iron  sliding  along  a  brace  near  the  center  of  the  frame.  The  tandem  attachment 
is  connected  to  the  front  harrow  in  a  moment's  time. 

Scrapers  for  cutaway  gangs  will  be  supplied  as  special  equipment  at  extra  cost.

Osborne  orchard  disk  harrow  with  gangs  set  for  out-throw, 
as  used  for  regular  disking 

Orchards  require  the  use  of  a  disk  harrow  specially  designed  for  orchard  cultivation. 
Horses  cannot  be  driven  very  close  to  trees  and  vines,  but  it  is  necessary  that  the  ground  be 
stirred  under  the  branches.  The  Osborne  orchard  disk  harrow  is  built  with  a  low,  wide  frame 
of  bar  steel,  especially  braced  to  make  it  rigid.  It  will  pass  under  very  low  branches  without 
doing  damage.  With  the  regular  frame  the  width  of  cut  may  be  extended  to  six  feet,  but  l>y 
means  of  the  extension  frame  an  extreme  width  of  cloven  feet  six  inches  can  be  reached.  This 
extension  frame  is  attached  in  a  short  time  and  permits  of  cultivating  close  to  the  trunks  of  trees 

without  damage  to  the  branches.  The 
Osborne  orcliard  disk  harrow  will  do 
the  finest  kind  of  work  in  keeping  the 
orchard  free  of  grass  and  weeds. 

Gang  Adjustments 

The  gangs  may  be  set  for  in-throw 
oi-  out-throw.  Either  the  inner  or 
outer  ends  of  the  gangs  may  be  tilted 
up  for  making  i-idgcs  or  ditches,  or 
cultivating  shallow  close  to  the  trees 
and  deeper  farther  away.  The  gangs 
may  be  set  close  together  and  ar- 
ranged for  out-throw.  Then  it  will 
do  the  same  work  as  a   regular  disk

Gang  Bearings 

The  gangs  are  given  ample 
bearing  surface.  These  bear- 
ings are  fitted  with  oil-soaked 
hard  maple  bushings  which 
will  last  a  long  time  if  prop- 
erly lubricated.  The  grease 
cup  places  the  hard  oil  at  the 
center  of  the  bearing  where  it 
is  well  disti-ilnited  over  the 
wearing  suii'ace.  The  wood 
bushings  are  inexpensive  to 
renew  when  finally  worn  out.

change  the  angle  of  the  gangs 
thi'ough  an  adjustable  crank 
wiiich  is  clamped  to  a  square 
bar  running  half  the  length 
of  the  frame.  The  levers  are 
long  and  make  shifting  of 
the  gangs  easy.  The  quad- 
rants have  fine  notches  for 
close  adjustment. 


Each  gang  is  regularly  equipped  with  a  shield  to  avoid  damaging  low-hanging  fruit  and 
branches.  When  etpiipited 
with  the  extension  frame,  it 
is  advisal)le  to  use  frame

Osborne  Disk  Harrow  Forecarriage 

Nearly  all  fields  are  so  rough  as  to  cause  the  disk 
harrow  to  draw  unsteadily  and  the  tongue  to  whiji 
and  worry  the  horses,  giving  them  sore  shoulders 
during  early  spring  work.  It  is  to  free  the  horses 
of  this  action  of  a  stiff  tongue  and  varying  draft  of 
the  disk  harrow  that  this  forecarriage  is  being  pur- 
chased with  nearly  all  Osborne  disk  harrows  sold,  or 
for  those  already  in  field  use.  It  keeps  the  harrow 
running  smoothly  and  in  line,  and  makes  it  easier  to  °;;  'jpf';'"'4"-3 
work  into  corners  and  close  to  fences. 

The  forecarriage  is  used  with  or  without  a  pole.  A  pole  is  essen- 
tial only  in  very  hilly  sections  of  the  country  when  driving  to  or 
from  fields.  It  is  regularly  equipped  with  pole  plates  for  two  horses 
when  a  tongue  is  ordered.  Set-over  irons  for  three  or  five  horses  are 
special  pole  equipment.  These  set-over  irons  make  it  possible  to  use 
the  pole  with  any  number  of  horses  desired.  The  wheels  of  the  fore- 
carriage  turn  completely  under  the  stub  tongue  in  making  a  short  turn. 
It  is  not  intended  that  the  forecarriage  should  interfere  with  the 
direct  line  of  draft  from  the  horses'  tugs  to  the  gang  connection.  It 
should  be  adjusted  to  carry  the  weight  of  the  front  end  of  the  harrow 
and  press  on  the  ground  just  enough  to  keep  the  harrow  working  in 
line  without  adding  to  the  draft  of  the  implement.  To  produce  this 
result  the  stub  tongue  and  draft  connection  are  adjustable  to  several 
heights  on  the  vertical  shaft.  The  steel  clevis  also  has  a  range  of 
up-and-down  adjustment.  Thus  the  Osborne  forecarriage  is  suited  to 
use  with  any  size  team  and  various  types  of  disk  harrows.  The  clevis  is 
so  attached  as  to  hold  the  whifHetrees  off  the 
ground  and  the  horses'  heels.  The  vertical  shaft  is  pivoted  in  the  fore- 
carriage  axle,  giving  limited  swivel  action  when  disking  uneven  ground. 
The  stub  axles  are  cast  in  the  hubs  with  the  spokes,  making  them 
as  one  piece  with  the  steel  wheels.  They  are  inserted  in  the  bearings 
and  keyed  with  take-up  washers  near  the  middle  of  the  axle.  This 
permits  the  wheels  to  act  independently  and  produce  flexibility  when 
working  rough  fields.  The  take-up  washers  provide  for  making  the 
axles  tight  when  they  have  become  worn.    The  grease  cups  force  grease 

into  the  axle  bearings  where  it 
will  be  distributed  thoroughly. 
Dust  caps  exclude  dirt  and  pre- 
vent the  axles  from  cutting  out.

Osborne  Peg-Tooth  Harrow 


Two-section  Osborne  peg-tooth  harrow,  having  35  teeth  to  a  section 


Oftentimes  light  soil  is  in  such  good  condition  after  plowing  that  running  over  it  witli  a  peg- 
tooth  harrow  will  produce  a  good  seed  bed,  but  usually  the  peg-tooth  harrow  should  be  preceded 
by  the  disk  harrow  and  the  ground  pulverized  deep  before  smootiiing.  The  peg-tooth  harrow 
is  the  most  efficient  implement  for  breaking  the  lumps  turned  ui)  Ijy  the  disk  harrow.  To 
properly  do  the  woi'k  of  smoothing,  the  harrow  sections  should  l>e  stiff  so  tliat  vigdious  action 
is  given  when  passing  over  irregularities  on  the  surface. 

The  Osborne  peg-tooth  harrow  is  l)uiit  with  the  intention  that  every  tooth  sliall  be  held  to 
do  a  thorough  job  of  harrowing.  The  tooth  bars  are  of  channel  steel.  They  cannot  twist  out 
of  shape,  nor  will  they  check  or  crack  like  wood  bars  and  let  the  teeth  become  loose. 

The  rigidity  of  a  section  of  the  Osborne  peg-tooth  harrow  is  due  to  two  stiffening 
bars  placed  near  the  ends  of  the  section  which  liold  the  tooth  bars  from  acting  indepen- 
dently. This  feature  meets  the  approval  of  every  farmer  who  sees  it.  Through  these 
stiffening  bars  any  strain  that  would  have  come  on  one  tooth  bar  when  a  tooth  struck  a 
hard  spot  or  obstruction,  is  distributed  to  all  of  the  tooth  bars  in  the  section.  Thus,  any 
bending  force  that  may  come  on  a  tooth  bar  cannot  twist  the  bar  out  of  shape. 

Each  tooth  fits  into  notches  in  tlie 
edges  of  the  tooth  bar  and  is  clamped  in 
place  by  a  clip,  shaped  to  fit  closely  about 
the  tooth,  and  drawn  up  light  with  two 
nuts.  The  teeth  cannot  work  loose.  The 
heads  of  the  teeth  are  upset  to  further 
insure  against  their  becoming  lost.  Either 
J^-inch  square  or  fs-inch  diamond-shaped 
teeth  can  be  furnished. 

Each  section  is  equii)ped  with  foui- 
runner  teeth  for  transporting  the  harrow 
to  and  from  fields,  without  wearing  down 
the  tooth  points  on  macadam  roads  or 
loading  the  harrow  into  a  wagon.     The  '^ '■•"''°"  ^t^nTatuchren,  *"""""  ""^

runner  teeth  do  the  same  work  as  other  teeth 
when  set  for  harrowing. 

The  draw  bar  is  attached  to  the  sections  in 
such  a  way  that  it  will  not  unhook  when  turn- 
ing corners.  The  draw  bail  is  made  up  of 
heavy  jointed  rods  and  chain,  furnishing  a 
substantial  draft  connection. 

Slip  Notch  Lever   Quadrant 

Each  section  has  a  long  lever  for  changing 
the  slant  of  the  teeth.  The  quadrant  has  slip 
notches  so  that  it  is  only  necessary  to  pull  back 

on  the  lever,  without  lifting  the  hand  latch,  when  setting  the  teeth  to  do  harrowing.     The  first 
notch  is  deep  and  locks  the  lever  for  transporting  on  the  the  runner  teeth.

They  are  easily  bolted  to  the  tooth  bars. 
Orchard  guards  are  special  equip- 
ment and  cost  extra. 

Riding  Attachment 


The  tediousness  of  plodding  all  day 
behind  a  peg-tooth  harrow  is  avoided 
by  fastening  a  riding  attachment  to  the 
draw  bar  wiiii  only  two  bolts.  The  large  steel  wheels  make  easy 
riding  and  add  little  to  the  draft.  The  attachment  is  practically 
all  steel.  The  wheels  are 
lubricated  by  hard  oilers 
and  swiveled  to  turn  and 
follow  the  rear  of  the  har- 
row around  corners.  The 
cost  of  this  attachment  is 
slight.

Osborne  Spring -Tooth 


larrow 


Osborne  spring-tooth  harrow 


A  tillage  tool  with  lively  lifting  action;  the  best  implement  for  stony  or  cloddy  ground;  a 
weed  killer;  destroyer  of  volunteer  wheat  and  fine  for  thinning  winter  wheat;  a  first-class 
alfalfa  cultivator  and  a  preparer  of  good  seed  beds. 

The  Osborne  spring-tooth  harrow  is  built  up  of  an  angle  steel  frame  with  steel  pipe  tooth 
bars  attached  to  the  frame  by  malleable  castings.  The  front  of  the  frame  is  given  an  upward 
slope  to  allow  it  to  pass  over  trash  and  clods.  To  the  bottom  of  the  frame  is  bolted  a  removable 
steel  runner  to  protect  it  from  wear.  This  can  be  renewed  at  any  time  should  it  become  worn 
out.  A  portion  of  the  frame  of  the  left-hand  section  is  cut  out  and  a  steel  bar  extended  over 
the  top  at  this  point  to  permit  trash  clearance  from  the  middle  of  the  harrow,  and  to  make  the 
frame  rigid.  The  sections  are  hinged  together  to  give  flexible  action  on  rough  ground,  assuring 
that  all  of  it  will  be  cultivated.  The  hitch  is  so  placed,  with  holes  for  adjusting  the  line  of  draft, 
that  any  desired  action  of  the  harrow  is  possible.  The  levers  are  long,  making  it  easy  and 
convenient  to  change  the  cutting  depth.     The  quadrants  have  fine  notches  for  close  adjustment. 

The  teeth  are  made  of  oil-tempered  steel  with  sufficient  length  and  resiliency  to  produce  a 
lively  action  in  the  soil.  They  are  held  to  perform  their  work  by  the  rigid  steel  frame  and 
will  give  excellent  results  in  very  hard  ground.  A  feature  which  aids  in  working  hard  ground 
is  the  spanner  grip  by  which  the  teeth  are  attached  to  the  tooth  bars.  You  will  notice  this 
grip  in  the  illustration  above.  The  spanner  grip  puts  the  twisting  strain  on  the  pipe  bar 
rather  than  on  the  tooth  and  the  tooth  bolt.  A  slot  in  each  tooth  permits  setting  the  teeth  to 
penetrate  to  a  lesser  or  greater  depth  than  with  the  usual  changes  by  the  levers. 

Special,  reversible,  double-pointed  teeth  can  be  supplied,  which  practically  doubles  the  use- 
fulness^ of  one  set  of  teeth.     These  are  furnished  at  a  slight  additional  cost.

This  is  the  Osborne  spring-tooth  harrow  with  riding  attachment,  and  the  levers  and  quadrants 
})hiced  nearer  the  front  where  they  may  be  easily  reached  from  the  driver's  seat.  This  attach- 
ment may  be  purchased  with  the  harrow,  or  can  be  added  at  any  time.  The  sulky  attachment 
is  liuilt  in  two  sizes — one  size  for  the  1.5-tooth  harrow,  and  another  for  the  17  or  23-tooth 
harrows.  If  ordering  a  sulky  attachment  for  a  harrow  you  already  have,  be  careful  to  state 
which  size  your  harrow  is. 

The  weight  of  the  driver  may  be  carried  by  the  sulky  attachment  on  soft  ground,  or  thrown 
on  to  the  teeth  in  hard  ground.  The  wheels  are  within  the  harrow  and  do  not  travel  on  the 
cultivated  ground.  The  runner  shoes  in  front  assist  in  maintaining  an  even  depth  of  cultivation 
and  make  it  easy  to  t,i-ansport  the  harrow  to  and  from  fields.

Osborne  Combination  Harrow 


Osborne  combination  harrow 


The  Osborne  combination  harrow  does  the  same  effective  work  as  a  i-egular  spring-tooth 
harrow.  It  lifts  clods  to  the  surface  and  lets  the  finer  compact  soil  fall  below  where  it  makes  a 
first-class  seed  bed.  After  the  clods  are  lifted  to  the  surface  hy  the  resilient  action  of  the  spring 
teeth,  the  row  of  trailing  teeth  in  the  rear  breaks  up  the  lumps  while  they  are  fresh  and  leaves 
a  smooth  surface  without  using  a  peg-tooth  harrow.  This  puts  the  ground  in  good  condition 
for  the  drill. 

The  Osborne  combination  harrow  is  built  with  a  fi-ame  of  one  piece  channel  steel  to  each 
section,  and  tooth  Ijars  are  of  the  same  material.  The  frame  is  raised  high  to  give  ready  clear- 
ance to  trash.  The  teeth  are  held  to  the  tooth  bars  by  a  clip  and  two  bolts  which  permit  adjust- 
ing them  to  make  up  for  wear  at  the  points.  Each  section  has  a  long  lever  and  a  quadrant  with 
fine  notches  for  close  adjustment. 

Each  trailing  tooth  is  attached  to  the  channel  steel  bar  across  the  rear  by  a  bolt  and  a  clip 
which  fits  into  the  bar  and  holds  the  tooth  secure.  The  slant  of  the  teeth  may  be  adjusted  by 
using  the  different  holes  in  the  brace  from  the  trailing-tooth  bar  to  the  frame.  The  trailing 
teeth  are  made  of  round  steel  with  a  head  on  one  end  to  prevent  their  slipping  through  the  clips 
and  Ijecoming  lost. 

Two  runner  shoes  are  swiveled  with  the  adjustable  hitch  at  the  front  corners  of  each  section. 
These  keep  the  harrow  penetrating  at  an  even  depth  and  hold  it  to  run  steadily.  The  spring 
teeth  can  be  raised  high  and  the  runner  shoes  and  trailing  teeth  will  carry  the  harrow. 

The  Osborne  combination  harrow  is  furnished  in  two  and  three  sections.  Two  sections  culti- 
vate a  width  of  ,5  feet,  6  inches,  and  3  sections  8  feet,  5  inches.

Osborne  Vineyard  Spring-Tooth  Harrow 


This  harrow  is  made  up  of  one  section  of  the  regular 
Osborne  spring-tooth  harrow  and  fitted  with  a  draw  bail. 
It  is  especially  adapted  for  use  in  vineyards,  orchards, 
nurseries,  and  where  a  larger  harrow  is  unnecessary.  It 
is  built  in  7,  9  and  Ti-tooth  sizes  and  will  be  furnished 
with  steel  handles  on  special  order. 

The    7-tooth  harrow  cuts  1  foot,  11  inches. 

The    9-tooth  harrow  cuts  2  feet,    6  inches. 

The  12-tooth  harrow  cuts  3  feet,     4  inches.

CoUIngs  Alfalfa  Tooth 


The  oval  shape  of  the  tooth  permits 
it  to  scour  readily  and  also  stiffens 
it  so  that  it  penetrates  hard  ground 


The  Osljorne  spring-tooth  harrow  has  been 
perfected  as  an  alfalfa  cultivator  by  fitting  it 
with  the  Collings  tooth  for  alfalfa  cultivation. 
This  tooth  has  the  resiliency  of  the  regular 
tooth,  though  it  is  stiffened  by  a  crimp  along 
the  portion  which  penetrates  the  ground. 
While  this  holds  the  tooth  to  penetrate  better, 
it  also  avoids  damage  to  alfalfa  plants  by  pre- 
senting a  curved  face  against  the  crowns  and 
will  not  tear  them  out.  The  point  is  oval- 
shaped  and  not  liable  to  cut  off  many  roots. 
The  point  and  shank  clear  themselves  of  trash 
and  scour  clean. 

The  Osliorne  spring-tooth  harrow,  with 
Collings  alfalfa  teeth,  loosens  the  ground 
without  any  tendency  to  pack  it.  Being  in 
sections,  it  adjusts  itself  to  uneven  ground 
much  better  than  a  stiff  frame  cultivator. 

The  Collings  alfalfa  teeth  are  furnished  on 
special  order.  Be  sure  to  ask  for  the  correct 
number  of  teeth  when  ordering.

Expanding  Device 

The  expanding  device  holds  the  side  bars  rigidly  in 
place  because  of  the  lever  lock  and  double  expanding 
bars.  By  the  expanding  lever  the  width  of  cultivation 
can  be  changed  instantly  to  any  point  within  the  range 
of  the  cultivator  and  locked  without  stopping  the  horse. 
Notches  on  the  locking  bar  are  close  together  so  that 
the  outside  shovels  can  be  run  near  to  plants,  even  when 
cultivating  narrow  i-ows.  The  lever  lock  and  double 
expanding  liars  account  for  the  rigidity  of  Osborne  culti- 
vators in  any  width  of  row.

Cross  section  of  the  shovel  used  on  the  Osborne 

cultivators,  showing  that  the  metal  is  thicker 

in    the    center    than    at    the    edges 


Similar  construction  is  used  in 
the  moldboards  and  horse  hoe.  Shanks 
for  the  moldboards  are  swiveled  so 
any  degree  of  hilling  slant  can  be 
given  them. 

Special  Attachments 

A  depth  regulator  is  sometimes 
desired  for  use  with  cultivators 
Xos.  55,  75  and  95.  It  is  furnished 
when  ordered,  at  added  cost. 

A  3-inch  shovel  is  regularly  fur- 
nished on  the  5,  7  and  9-shovel  cul- 
tivators. Shovels  1,1>^,1^,  2,  2^, 
and  4  inches  wide  will  be  supplied 
on  special  order.

on  special  order 


Shovels 


Osborne  cultivator  shovels  ai-e  thick  through  the 
middle  and  thinner  at  the  edges.  This  construction 
keeps  the  points  sliarp  as  they  wear  and  holds  the 
shovels  to  their  shape  in  stony  fields.  Shovels  are 
double  pointed.  The  shanks  are  curved  to  fit  the 
shovels  and  hold  them  straight.  A  square-headed 
bolt  fastens  the  shovel  to  the  shank.

Osborne  1  4-Tooth 
Cultivator 


Where  it  is  desired 
to  stir  the  ground  deep 
without  throwing  the  dirt  either  way,  the  14-tooth  culti- 
vator is  the  right  tool  to  use.
